A conservative system consists of a frictionless crane lifting a load of bricks at a construction site. The amount of work done by the crane against gravity is(1 point) Responses is equal to the energy stored in the bricks is equal to the energy stored in the bricks less than the energy stored in the system less than the energy stored in the system greater than the energy stored in the bricks greater than the energy stored in the bricks equal to the kinetic energy of the system
